It is often said that all Bible versions are basically
the same, that their differences are just minor wording changes.
Read the following comparison between the King James Version and
the best-selling modern Bible translation, the New International
Version, and then decide for yourself whether or not this is true.
We have added bold text to assist the reader in recognizing changes.

Question: Aren't some of these things included in the NIV in the footnotes?

Answer: That is not the same as including them in the text. When
a young Christian sees these passages have been moved to
the footnotes, he or she will assume that they are probably
not really part of God's Word. After all, the translators
did not include them in the text, but simply implied that
"some" manuscripts include them. What they are
not told is that the vast majority of texts
used by the early church included these words. They are
God's Words!

This is only a very small sampling of the many changes between these versions.

attacks the deity of Christ, and cuts away at the foundations of the Christian
church, read

Destroyed" by Chick Salliby.
